Difference between a RAM and ROM

RAM stands for random access memory and ROM stands for read only memory, are two different types of memory that are used in computers. A buyer should learn about the differences between the RAM and ROM in computers and other devices. RAM is volatile memory, which means that the data can be deleted. ROM is the non-volatile part of the memory where the permanent data that is necessary for operating the computer system is written. Another difference is that RAM needs electricity in order to work, so the information stored in RAM is lost whenever the computer is turned off. ROM does not need electricity in order to preserve the data, so it retains the information when the computer is turned off.
 
RAM or random access memory, as the name suggests, is the one that can be randomly accessed, altered and the changes there in can be saved. It is thus used to store information on the devices.
ROM or read only memory, is the one that can only be read and is therefore the permanent memory of the device that can neither be altered nor deleted.
